CONSTRUCTIVE
I'd like if the movement speed would be faster.
Having interactions on the doors and other things that seem like I should be able to interact with them would help know if I'm doing the wrong or right thing.
LIKED
I was really impressed with the sprite work once I got into battle.
The arena itself representing the state of the opponent is a really good touch!
The level of gruesome is a huge charm point here.
FINAL
I see the vision, it's very gruesome that feels remniscent of early flash games in both the tone and humour - good job!
